Owens Corning Composite Materials (OC, Toledo, Ohio) introduced at COMPOSITES 2013 its reengineered OptiSpray multi-end glass roving, based on Advantex glass fiber. The original roving was optimized to work with any resin in any application via a design of experiments (DOE) approach. To achieve optimal sizings, OC developed three versions, reengineered with a smaller filament diameter: OptiSpray, OptiSpray H and OptiSpray F (for faster wetout). The rovings reportedly chop faster with less fuzz, and stay together until they hit the chopper gun, which leads to faster throughput. Fiber conformity reduces spring back, the roving’s better mechanicals are said to translate to fewer chopper-gun blade changes, and the sizing's increased softening point spells better performance in high ambient shop heat and humidity. Less air is incorporated, so rollout is faster.
